Emily Atack wakes up with 'Holly Willoughby and Emma Bunton on bum' after incredible transformation

Emily Atack hinted at a heavy night as she underwent an incredible transformation over the weekend. The former Inbetweeners actress was barely recognisable when she took to Instagram with some snaps as she headed to Keith Lemon's 50th birthday party.

Comedian and TV star Leigh Francis celebrated his special day with a fancy dress bash attended by a huge number of his celebrity pals including Emily, Emma Bunton, Holly Willoughby, Phillip Schofield, Paddy McGuinness, Tess Daly, Vernon Kay, Laura Whitmore and Will Mellor.

And Emily looked absolutely sensational as she transformed into Hollywood icon Marilyn Monroe for the night. The 32-year-old could be seen with perfectly curled locks which were shorter than normal and showed off her pearl drop earrings.
